If you have a page to discuss the role of a particular type of work, area, field of study, etc. (dependent on your framing) in your concentration, consider some of these topics for your reflection:
What is the importance of the theme to your work?
How has your understanding in this area changed over time?
Which examples of work relate to this particular area of your interest or inquiry?
What do the artifacts show - that is, what should the reader look for?
Share which courses you took in this field. Why were they were important to you?
Which activities – both in and out of class – contributed most to your learning in this area?
or anything else applicable to the theme. Include, and discuss, examples of your work that you embed.
